Chronic Myelogenous Leukemia Treatment (PDQ®): Treatment - Patient Information [NCI] - General Information About Chronic Myelogenous Leukemia
Signs and symptoms of chronic myelogenous leukemia include fever, night sweats, and tiredness.
These and other signs and symptoms may be caused by CML or by other conditions. Check with your doctor if you have any of the following:
- Feeling very tired.
- Weight loss for no known reason.
- Night sweats.
- Pain or a feeling of fullness below the ribs on the left side.
Sometimes CML does not cause any symptoms at all.
Most people with CML have a gene mutation (change) called the Philadelphia chromosome.
Every cell in the body contains DNA (genetic material) that determines how the cell looks and acts. DNA is contained inside chromosomes. In CML, part of the DNA from one chromosome moves to another chromosome. This change is called the "Philadelphia chromosome." It results in the bone marrow making an enzyme, called tyrosine kinase, that causes too many stem cells to become white blood cells (granulocytes or blasts).
The Philadelphia chromosome is not passed from parent to child.
Philadelphia chromosome. A piece of chromosome 9 and a piece of chromosome 22 break off and trade places. The bcr-abl gene is formed on chromosome 22 where the piece of chromosome 9 attaches. The changed chromosome 22 is called the Philadelphia chromosome.
Tests that examine the blood and bone marrow are used to detect (find) and diagnose chronic myelogenous leukemia.
The following tests and procedures may be used:
